I know one person requested spacebar to be able to be held and released, but I suppose for most cases it's not nessary.
What I do think is rather nessary is to be able to hold down arrow keys. (might as well just have it able to hold down any button would be good too in my opinion. You should have a new command: hold, to be used with release. And press would just be used by itself to simulate tappign the key.)
Certain things, such as Macromedia Flash applets, do not register keypresses of arrows unless held down in certain situations. This may not be true in all situations though.
I have tried using "up * 50", "up*8", Etc. but it doesn't move the object in question at all. Sometimes it might, but then it would only move up one, and it's random, which is strange.
